OK, forget it, that was my fault.
The release date of the .inf file of driver 20.4.1 is 18th Aug 2015 for 82579, whatever in Win7/8/8.1/10 and not 2nd May 2014 anymore.
And finally great, over 1 year lasting horrible dropout catastrophe solved!
No more 5ms-6ms NDIS.sys taking up.
Now all drivers are just taking up only max. around 0.1ms - 0.2ms, and NDIS.sys is now usually stably in 0.1ms, very stable.
Dropouts in this 1 year and 2 months all gone, steady clear and stable sounds, so I can revive my recording works now.
I found this driver in the list of 1218-V but apply to 82579 too!
But I wonder how Intel finally solve this problem, any personnel of Intel say something here?
